DETAILED DESCRIPTION OF SELECTED EMBODIMENTS

It will be readily understood that the components of the present invention, as generally described and illustrated in the drawings herein, could be arranged and designed in a wide variety of different configurations. Thus, the following more detailed description of the embodiments of the system and method of the present invention, as represented in the drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of various embodiments of the invention. The illustrated embodiments of the invention will be best understood by reference to the drawings, wherein like parts are designated by like numerals throughout.

Referring to FIGS. 1-6, in selected embodiments, a seating system 10 in accordance with the present invention may include an anchor 12, a suspension system 14, and a seat 16. An anchor 12 may connect a seating system 10 to a supporting structure 18. A supporting structure 18 may be a tree, branch of a tree, post, pole, arbor, rail, rock, or the like. An anchor 12 may be configured to connect to a supporting structure 18. Accordingly, an anchor 12 may be adapted to the characteristics of a supporting structure 18.

For example, in certain embodiments, a supporting structure 18 may be a tree (e.g., a main trunk of a tree). Accordingly, an anchor 12 may include a strap 20 configured to wrap around a tree. In selected embodiments, an anchor 12 may include a clasp 22, buckle 22 (e.g., a cam buckle, D-ring buckle, quick release buckle, or the like), or other connector 22 that may enable a strap 20 to be securely fastened (e.g., connected and/or tightened) around some portion of a supporting structure 18.

An anchor 12 may include one or more connection points 24. For example, an anchor 12 may include a first connection point 24 a and a second connection point 24 b. A connection point 24 may provide a location for a suspension system 14 or some portion thereof to engage an anchor 12. In selected embodiments, one or more connection points 24 may include a hook 26 (e.g., a metal hook) connected to a strap 20 by a tether 28.

In certain embodiments, one or more connection points 24 may be selectively moveable along a strap 20. This may enable the one or more connection points 24 to be moved to optimal or desired positions to accommodate the particular dimensions (e.g., diameter) of a supporting structure 18 to which an anchor 12 is applied. In selected embodiments, a connection point 24 may be moved along a strap 20 by sliding a tether 28. Thus, a tether 28 may engage (e.g., loop around) a strap 20 without being permanently fixed to a particular location on the strap 20.

An anchor 12 may be formed of any suitable material or combinations of materials. For example, in selected embodiments, a buckle 22 and hook 26 may be formed of metal, while a strap 20 and one or more tethers 28 may be formed of flat polymeric webbing. In certain embodiments, a rubberized or other grip-enhancing material may be applied to a strap 20 to enhance the ability of the strap 20 to grip a supporting structure 18. This may be accomplished by adhering or securing a rubberized or grip material on an inner surface of a strap 20 or by sliding one or more sleeves (e.g., relatively tight fitting sleeves) of rubberized or grip material onto a strap 20.

A suspension system 14 may connect a seat 16 to an anchor 12. Accordingly, a suspension system 14 may transfer the weight of a user 30 to an anchor 12 so that the anchor 12 may, in turn, transfer the load to the supporting structure 18. In selected embodiments, a suspension system 14 may include one or more tethers 32 and a spreader 34.

For example, a suspension system 14 may include a first tether 32 a and a second tether 32 b. A first tether 32 a may connect a first side 36 a of a seat 16 to a first connection point 24 a. A second tether 32 b may connect a second side 36 b of a seat 16 to a second connection point 24 b. A spreader 34 may extend between the first and second tethers 32 a, 32 b to space the first and second sides 36 a, 36 b of a seat 16 away from each other to produce a more comfortable seating experience for a user 30.

In selected embodiments, a suspension system 14 may be configured to easily and securely engage an anchor 12. For example, the upper ends of the first and second tethers 32 a, 32 b may each be or include a ring 38 (e.g., a metal ring) that may be easily hung from a hook 26 of a corresponding connection point 24 of an anchor 12. Similarly, the lower ends of the first and second tethers 32 a, 32 b may each be or include a ring 40 (e.g., a metal ring) that may form a strong connection with a corresponding side 36 a, 36 b of a seat 16.

In certain embodiments, first and second tethers 32 a, 32 b may each include a spreader interface 42. A spreader interface 42 may provide a location for an end of a spreader 34 to engage a corresponding tether 32. In selected embodiments, an end of a spreader 34 may be or include an extension 44 and a spreader interface 42 may be or include an aperture sized and shaped to receive the extension 44. Accordingly, an extension 44 of a spreader 34 may be inserted within an aperture of a spreader interface 42 in order to secure that end of the spreader 34 to a corresponding tether 32.

In selected embodiments, an upper portion 46 of a tether 32 may be connected to a lower portion 48 of the tether 32 by a ring 50 (e.g., a metal ring). A bridge material 52 may also extend to connect an upper portion 46 to a lower portion 48. An aperture formed in the bridge material 52 may be sized and shaped to receive an extension 44 of a spreader 34. Thus, in certain embodiments, a ring 50, a bridge material 52, an aperture in the bridge material 52, and selected portions of the upper and lower portions 46, 48 of a tether 32 may form a spreader interface 42.

In selected embodiments, a spreader 42 may be a segmented rod. That is, a spreader 42 may comprise various segments 54 that may be separated from one another in order to reduce the overall length of the spreader 42. This may enable a seating system 10 to be fit within a relatively small space for transport and storage.

A suspension system 14 may be formed of any suitable material or combinations of materials. For example, in selected embodiments, various rings 38, 40, 50 and various components of a spreader 34 may be formed of metal, while one or more tethers 32 may be formed of flat polymeric webbing. Alternatively, or in addition thereto, one or more components of a spreader 34 may be formed of fiberglass or the like.

In selected embodiments, a seat 16 may be a mesh, net, or weave formed using various intersecting pieces of flat polymeric webbing. Multiple pieces of flat polymeric webbing that extend side to side may converge at the first and second sides 36 a, 36 b of a seat 16. This may enable the weight of a user 30 to be easily and securely transferred to the corresponding tethers 32 of a suspension system 14. In other embodiments, a seat 14 may be formed of a fabric material cut and/or reinforced as necessary to securely transfer the weight of a user 30 to the corresponding tethers 32 of a suspension system 14.

A seating system 10 in accordance with the present invention may be readily portable. For example, a seating system 10 may be compactable and relatively light so that a user may carry the seating system 10 in a pack (e.g., in a relatively small stuff sack or the like carried within a backpack) during outings (e.g., day hikes, multi-day hikes or camps) in the woods. Accordingly, when the user would like to sit or rest, he or she may find a suitable tree or the like and deploy the seating system 10.

Deploying a seating system 10 in accordance with the present invention may include: (1) wrapping the anchor 12 around a portion of a tree 18 (e.g., wrapping the anchor 12 horizontally around a trunk of a tree 18); (2) securing the anchor 12 around the portion of the tree 18 (e.g., securing the anchor 12 horizontally wrapped around the trunk of the tree 18); (3) substantially vertically suspending, by the first tether 32 a, a first end of the seat 16 from a first connection point 24 a of the anchor 12; and (4) substantially vertically suspending, by the second tether 32 b, a second end of the seat 16 from a second connection point 24 b of the anchor 12.

Once a seating system 10 is deployed, a user may sit on the seat 16 thereof. During such sitting, an anchor 12 may transfer to the tree 18 all weight (or substantially all weight) applied by the user to the seating system 10. In situations where a trunk of a tree 18 extends vertically or substantially vertically, gravitational forces may urge or bring a user sitting on a seat 16 toward the tree 18 (e.g., toward the trunk of the tree 18) such that a back of the user is proximate or rests against the trunk of the tree 18.

Referring to FIGS. 7-9, in selected embodiments, a connector 22 may comprise a cam buckle so that a user may more easily cinch or tighten an anchor 12 around a supporting structure 18 (e.g., around a trunk of a tree) and, thereby, prevent slippage of the anchor 12 with respect to the supporting structure 18 during use. In certain embodiments, a connection point 24 of an anchor 12 may be a loop of metal, a loop of fabric (e.g., of flat polymeric webbing), a portion of a strap 20, or the like. An upper end of an upper portion 46 of a tether 32 may also include a loop of metal, a loop of fabric (e.g., of flat polymeric webbing), or the like. Accordingly, in selected embodiments, a carabineer 56 or the like may be used to connect an upper end of an upper portion 46 of a tether 32 to a connection point 24 of an anchor 12.

Referring to FIGS. 10 and 11, in selected embodiments, a spreader interface 42 may include backing material 58. Backing material 58 may connect to a tether 32 opposite bridge material 52. Accordingly, backing material 58 may reinforce a spreader interface 42 (and, therefore, increase the weight-carrying capacity of a tether 32) and assist in resolving forces imposed on a tether 32 may a spreader 34. For example, an extension 44 of a spreader 34 may extend through an aperture 60 (e.g., a grommeted aperture) in the bridge material 52 and contact the backing material 58. Accordingly, the backing material 58 may carry some of the load that would otherwise be imposed solely onto the aperture 60 in the bridge material 52. Also, during deployment of a seating system 10, backing material 58 may enable a user to quickly see how to orient and install a spreader 34 with respect to a spreader interface 42 since backward access to an aperture 60 in the bridging material 52 may be blocked by the backing material 58.

Referring to FIG. 12, in selected embodiments, tethers 32 may be configured so as to be adjustable in length. For example, in certain embodiments, a lower portion 48 of each tether 32 may be broken into two segments 48 a, 48 b. The two segments 48 a, 48 b may be connected to one another via a cam buckle 62. Accordingly, by pulling one of the two segments (e.g., the bottom segment 48 b) through the cam buckle 62, a user may shorten the corresponding tether 32. Alternatively, by releasing one of the two segments (e.g., the bottom segment 48 b) within the cam buckle 62, a user may lengthen the corresponding tether 32. In this manner, a user may adjust the length of each tether 32 individually and, thereby, select a desired seat height for a seating system 10 in accordance with the present invention.

The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects only as illustrative, and not restrictive. The scope of the invention is, therefore, indicated by the appended claims, rather than by the foregoing description.
